Recent applications

The two-moment cloud microphysics scheme has been used within the framework of the HD(CP)² (High Definition Clouds and Precipitation for Climate Prediction, ​http://www.hdcp2.eu) project to produce LES simulation data for the evaluation and benchmarking of ICON-LES (Dipankar et al., 2015). Figure 8 contains a snapshot from such a benchmark simulation, where three continuous days were simulated. The figure shows the simulated clouds including precipitation events on 26 April 2013 during a frontal passage. Moreover, cloud microphysics have been recently used for investigations of shadow effects of shallow convective clouds on the ABL and their feedback on the cloud field (doc/app/bcmref Gronemeier et al. 2016).

Figure 8: Snapshot of the cloud field from a PALM run for three continuous days of the HD(CP)² Observational Prototype Experiment. Shown is the 3-D field of q_c (white to gray colors) as well as rain water (q_r > 0, blue) on 26 April 2013. The simulation had a grid-spacing of 50 m on a 50 x 50 km² domain. Large-scale advective tendencies for θ_l and q were taken from COSMOE-DE (regional model of German Meteorological Service, DWD) analyses.
